Can someone tell me how to build a VIRTUAL LAN (virual network) using...

[Hasra]

...VirtualBox OR MS virtual PC 2007? detail? Using either VirtualBox OR Virtual PC 2007 I want to build a network with serveral virtual PCs. I'm using MS XP sp2 for all PCs (including host). For the case of Virtual PC 2007, I used MS loop-back adapter and tried to build a network but faild. For tha case of virtaulBox also result is same.































I search in google and found some interesting facts how to do it, but they couldn't help me. I'm still learning and want to do practicles on networking server accessing (i.e running web, e-mail servers etc). Therefore, if someone can kindly give me STEP-BY-STEP instructions on building a virtual network, it'll be a greate help to my studies.































AS a SUMMARY; I WANT A VIRTUAL NETWORK such that GUEST OS MUST BE ABLE TO TALK TO HOST and HOST SHOULD BE ABLE TO TALK TO GUEST OS. (i.e. ping should work from guest to host and host to guess)































regards.















Please give me any good references as well.































Thanks again.
